Ecological floating island

Technical Field

The utility model relates to an ecological management technical field especially relates to an ecological chinampa.

Background

The eutrophication of water is one of the most important problems facing the water environment treatment in China, and the eutrophication problem is particularly serious for rivers in urban areas, and reservoirs or lakes near the urban areas. Meanwhile, the traditional farming method and the unreasonable use of a large amount of chemical fertilizers and pesticides cause the increase of agricultural non-point source pollution, certain safety threat is caused to the water body, and the water environment problem needs to be solved urgently.

In various physical, chemical and biological water body treatment methods, the artificial ecological floating island has the characteristics of movable operation, long service life, low manufacturing cost, no secondary pollution and the like, is more and more concerned and becomes a research hotspot for water body ecological management; the aeration oxygenation can oxygenate the water body to accelerate the growth and the propagation of indigenous aerobic microorganisms so as to enhance the self-purification capacity of the water body, and is also widely applied to the ecological restoration of the water body. However, if the ecological floating island is used alone, the dissolved oxygen content in water cannot be greatly increased due to the ecological floating bed of pure plants, so when the dissolved oxygen content in the water is not high, microorganisms in a biological membrane of a plant root system are always in a facultative or anaerobic level, and the rate of decomposing pollutants in the water is reduced; if the microporous aeration technology is used alone, although the dissolved oxygen in the water body can be well increased, the microorganisms in the water body still cannot reach high concentration due to the fact that the microorganisms do not have fixed carriers, and the rate of decomposing pollutants in the water body is low.

Based on this, the combination of aeration technology and ecological floating island gradually becomes a big hotspot of current ecological restoration. The existing aeration technology comprises a fountain aeration technology and a micropore aeration technology, wherein the fountain aeration mode is that an underwater impeller is driven to rotate by an underwater motor, water is lifted and sprayed into the air, and oxygen is brought back to a water body by formed fine water drops so as to realize the aeration operation of the water body; the micropore aeration mode is for adopting air-blower (also being aeration machine) to send the air into gas transmission pipeline, gas transmission pipeline sends the air into micropore aeration pipe, micropore aeration pipe disperses the air with a large amount of microbubble forms to the aquatic, the microbubble is floated by the bottom of the pool upwards, it is abundant with the water contact, fully dissolve oxygen in the aquatic, and the rotation that has still increased rivers flows from top to bottom, the bottom is gone into to the hosepipe that is rich in oxygen with the upper strata, the water that contains oxygen around the micropore pipe is outwards diffused in the rotatory flow of the upper and lower flow of rivers simultaneously, realize the even oxygenation of water.

The continuous work of the blower needs more power supply, and the introduction of the commercial power into the ecological floating island faces a plurality of problems and is difficult to implement, so that a novel ecological floating island is urgently needed to improve the comprehensive processing capacity of the ecological floating island.
